HI if i join the Australian Military can i go to the British SAS to try out?

The British/Australian/New Zealand S.A.S do a lot of cross training around the world.The selection course for the British S.A.S are ran in February and August each year from Bradbury lines at Hereford.The British S.A.S recruit from the British armed forces mainly the Paras,Infantry and a few other units.Your best chance is to apply to join a English unit like the Parachute Regiment and then apply for selection from there.The S.A.S usually work in 4 man teams.1trained in weapons,1 in medicine,1 in signals and 1 in demolitions
